e convened portion or the spring. There since the frame i l'oi the panelis held under the tension of the spring 25, Y tendency thereof to rattleis entirely eliminated. i

F or the purpose of concealing the slot 1% when the panel 1 is removedto provide an open body,v there is preferably employed a closure plug2?" which comprises the spring retaining arms 28 and a bead-like headpor tion 29 similar in shape to the bead or moldh1g9 on the top edge of.the'door. Fig. 7 of the drawings shows this plug in perspective abovethe slot 14, and it will, of course,

' be understood that when the plug is inserted in the slot the latter isentirely closed, and the head portion Q9 thereof cooperates with thehead or molding 9 to'iorni a substantially unbroken surface.

ronl the foregoing, it will be apparent that one of the distinctivefeatures of the present invention'is the provision of a yieldableconnection betwen the sash panel and thedoor, which can be easily andquickly established and at the same time eliminate all possibility ofrattle when the door is closed. By way of forming this yieldableconnection it may be noted that when the sash is put in place on the topof the door, eachtenon element carried thereby enters one of theslotsli, which is slightly at one side of the center of the escutcheonplate 13, and moves downwardly in a substantially perpendicular planealong the vertical inner face of the spring as indicated in Fig. 4. Thesash panel I may,itherefore, assume a vertical position during thegreater part of its movement toward the top of the door, but uponreaching the rounded side of the convened holding hook 524, the end ofthe tenon becomes deflected against the face of the guard flange 23, asalso indicated by dotted lines in Fig. l. This forcing of the free endof the tongue 15 by the spring 25 into engagement with the wall 23,which as previously stated is located at one side of the outer edge 14aof the slot, thus causes the entire sash to tilt inwardly on the head 9and edge 14% of the slot l-i toward the door jainb, assuming of coursethat the door is open when the sash is applied thereto. .lgtcordingly itwill be apparent that the sziid outer edges 14 of the slots constitute afixed fulcrum for the l'enons 15 to tilt or cant to the sash, While theinner edges 14: of the slots lie in substantiallytlie same perpendicularplane as the inner vertical .t'ace 25*? of the s pping;

of the slot 1d withrelation tothe socket S,

and the Sitl011 of the rounded nose of the" convened holding portionElliot the spring 25, the ejnliresash is 'givenan inward tilt away fromthe vertical as clearly shown in Fig" 3 of the'drawines. when thedoor isi I f closed the upper edge of the sash or frame 1 will abut withtheshoulder provided by the rabbcted seat R in the top T of theautomobile body, and when the upper edge of the sash panel strikes thisabutment, itwill be forced outwardly against spring tension to theposition shown in Fig. .2 of the drawings. All of the greatest swingingmovement or play oi? the sash takes place at the upper free end thereof,while the lower edge having the groove 10 therein rocks on the beadingor molding Furthermore, owing to the relatively large dimensions of theclearance slot 12 beneath the entrance slot 2 14, the rocking movementof the sash on the heading 9 is not hindered, and the spring 25 in eachelement 11 is relatively recto exert its full influence on the free endof the tenons 15. When the sash is seated on the door and the free endof the tonguei15 is forced into frictional contact with the inner faceof the guard flange 23, the holding of the sash in position is assistedby the engagement of the rounded surface of the hooked portion 2% of thespring 25 engaging with the notch 19 of the tongue, thus preventingaccidental displacement.

1 Without further description, it is thought that the many features andadvantages of the present invention will be readily apparcut, and itwill be understood that various changes in the form, proportion andminor details oi construction may be resorted to without departing fromthe spirit of the inyention or scope of the appended claims.

economically and conveniently applied to articles of variousdescriptions.

In the present instance we have shown and described our invention asemployed for wrapping catalogues, books, pamphlets'or the like, but thisis merely for the purpose of illustrating, by a specific example, thefunction and mode of operation of the machine, and We wish it to bedistinctly understood that the invention is not limited in its usefulapplication to this particular pur pose, as the machine may be used forwrapping articles or objects of any character whatsoever and inconnection with which its the" employment may be deemed desirable oradva ntageous.

One purpose of the present invention is the provision of a machinewherein articles may be automatically and sequentially wrapped orincased so completely as to preserve the same against such soiling andin- I jury as is liable to occur under ordinary conditions attendantupon handling, transportation and storage. X I

Another object 'is to provide a machine wherein wrapper blanks or sheetsmay be successively and continuously fed into position to receive thearticles which in turn are sequentially and continuously presented tothe blanks or sheets, certain instrumentalities acting upon the sheetsand articles to accomplish the wrapping operation and then to convey thecompletely wrapped packages to asuitable'point of discharge Furthermore,we propose to provide amachine capable offincasing or inclosing anarticle in an envelop or bag-like container or wrapper, which is formedfrom a single' fiat blank or sheet during the wrapping operation;

A further object "of the invention is the provision of a machine whereinduring the wrapping operation certain over-lapped portions or sectionsof the wrapper are sealed or united through the medium of an adhesive,such as paste or the like, one end of the envelop or wrapper beingpreferably, though not necessarily, left unsealed, and being tucked inbeneath an adjacent portion of the envelop or wrapper to form a freefiapwhich may be withdrawn or opened to permit the ready removal of theinclosed article without the necessity of tearing or destroying suchenvelop-wrapper.

With the above recited objects and others of a similar nature in viewour invention consists in the construction, combination and arrangementof parts set forth in and falling within the scope of the appendedclaims.

--Before entering into a detailed description of our invention we willbrlefly state that it embodies, among other features, a

- table or support upon which may be placed a stack or-pile of the flatsheets or blanks from which the wrappers for the catalogues are to beformed one of the wrappers or blanks being shown in Fig. 27. Suitablesheet selecting and feeding'mechanis'm take these sheets successivelyand carry or present the same to sheet gripping devices mounted upon andtraveling with endless carriers, in

the present instance in the nature of chains traveling over suitablyarranged sprockets, the chains running beneath the bed of the machine.When a flat sheet or blank coming from the sheetf selecting and feedingmechanism is'g'rasped by one of these grippers it adjacent longitudinaledge opposite side portion of the lank, as is in-' is carried in thetravel of the latter to an adhesive or glue applying device WlllChapplies glue along one si e portion of the sheet and the latter is thencarried to a position directly beneath the catalogue-feeding mechanism.In the present instance this catalogue-feeding mechanism includes amagazine or hopper in which a stack or pile of the catalogues are placedin an approximately upright position or are up-ended. The catalogues arefed one at a time from this stack 0r pile and permitted to drop onto abracket-like support, each catalogue so dropped still maintaining itsapproximately upright position. When the sheet is brought beneath suchcatalogue, the latter is tilted or swung forward and downward andpermitted to drop fiat, or to a horizontal position upon the subjacentsheet, as diagrammatically indicated in Fig. 28.- The contin-- uedmovement of the endless carrier now conveys the sheet with the cataloguelying flat thereon away from beneath the catalogue feeding device andone end of the blank is folded over one end ofthe catalogue to form a.loose, free flap, as indicated in Fig. 29.

The wrapper with the catalogue thereon is now brought by the carrierinto position to have'one of the side sections of the blank folded overagainst the uppermost face of. the catalogue. The other or adhesivelycoated side portion ofthe blank is now folded inward so as to overliethe opposite side portion of the blank, both of these inwardly foldedside portions overlying the previously folded end portion ofthe blank,and the adhesive at the edge of the overlying side portion causes thelatter to adhere to the ortion of the dicated in Fig. 30; the initiallytucked-in end flap remaining free, that is to say, is

preferably not pasted or attached to the adjacent side sections of theblank by the adhesive. This leaves but one end portion of the wrapper tobe folded and fixed in position, and the continued travel of the carrierbrings this end portion or end flap into position to receive a strip or.coating of adhesive age so that it appears as shown in Fig. 33,

the package thus completely wrapped and sealed being discharged from themachine.

In connection with our machine,we proveyer D. Thiscarrier or conveyer Din the, present lns'tance embodies two pairs. of endtraveling carriers.

messes vide automatically operating means for automatically throwing themachine under- It is of course to be understood that the various powertransmitting connections and operating devices are so proportioned andtimed in their relative movements that the various operations vwill takeplace in the order described.

Referringnow to the accompanying drawings in detail, the letter Aindicates the frame of the machine which includes a suitablelongitudinally slotted bed B. At

. the front end 1, of the frame is located a sheet-feeding mechanismwhich is indicated as an entirety by the letter C, and is best shown inFigs. 1, 3 andll. It is to be understood that this sheet-feedingmechanism may be of any suitable type or character for feeding sheetsindividually and successively to the traveling carrier of the ma chine,and which earner is indicated as an entirety by the letter 1).

In the present instance we have shown a form, illustrating anddescribing only such parts thereof as may be necessary to understand itscoiiperation with the remainder of the present machine. In the type ofsheetfeedlng mechanism illustrated herein, the stack or pile of sheets,indicated at S, is mounted upon a reciprocating table 2 carried by theswinging frame 3, this frame being swung by means of the worm and sectorgear 4. As will be understood by reference to Fig. 11, as the tablereciprocates across the top of a suction pickerroll 5, the bottom sheetof the pile or stack is withdrawn by this picker 'roll. As will beunderstood by reference to Fig. 3, the picker roll is intermittentlysubjected to suction throu h the agency of a suitable suction pumpsuitably connected in driving relation with the power transmissiondevices of the machine, a suction pipe conventionally illustrated at pleading from this pump to the picker roll. As this arrangement ofsheet-selecting suction device is also'well known, it need not befurther described here in detail.

Referring again to Fig. 11, as each bottom sheet is selected or pickedofi from the bottom of the pile or stack by the picker roll it iscarried down between feed rollers 6 and 7 and the guides 8 and 9 to asheet gripper device E of the carrier or conlesschains 10-10 and 1111traveling over two pairs of sprockets adjacent opposite ends of theframe, the four endlesschains and as all of the sheet grippers travelinlongitudinally of and beneath the slotted ed of the machine: endlesschains, for instance, that made up of the two outside chains 10-10carries a series or set of sheet grippers E, while the other or insidepair of endless chains 11- 11 carries a series or set of other grippingdevlces such as are shown at'F, and which for the sake of convenienceand distinction, much iglliip and push the catalogues, books or the maybe termed pusher grippers inas- As shown in Figs. 5 and 6, at the rearend 1 of the machine is a sprocket shaft 12 which is driven through thetrain of gears 13, 14 and 15, the latter being on the power shaft 16. Onsaid shaft 12 are mounted the two sprockets 17 and 17' which form theoutside sprockets over which travel the chains 10-10, and th'esetwosprockets 17- 17 have adjustably connected therewith the inner pair ofsprockets 18' and 18 over which travel the inner pair' of chains 11. Theadjustment of the sprockets 18 and 18 relativeto the sprockets 17 and 17is accomplished through the racks 19 and inions 20, and it will be notedthat each 0 the sprockets 17 and 17 is slotted as at 21 for thereception of the adjusting screws 22 of the companion sprockets 18.-18.Inasmuch as the sheet grippers E are carried by the outside pair ofchains and the catalogue pusher grippers F are carried by the insidepair of chains, the adjustment of the sprockets just described enablesthe distance be tween a sheet gripper and a catalogue pusher to be madegreater or smaller. We might here mention that a sheet gripper E and avpusher gripper F constitute a pair of gripping devices for conveying thewrap per and a catalogue through the machine, and of course thesegrippers E and F are arranged in alternate relation for this pur pose.As shown in Fig. 12, at the opposite or frontend 1 of themachine theoutside pair of chains 10 travel over the sprocket members 23 whiletheinside pair of chains.

shaft 26 in turn drives other mechanisms of the machine, as will behereinafter described.

We will now describe the specific coir struction of one of. the sheet'ppers E, are similar a description of one will suflice.

Referring .especially to Figs. 23 and 26, itwill be seen that eachgripper comprises a carriage 27 provided with the four rollers 28, onepair at each side of the carriage;

One pair of as their purpose and function is to sheet of paper, thesestuds being. a apted to pro ect through the openings 32 in the spacedhoolrs 33 of the gripper. These hooks 33 which are adapted to clamp theforward edge portion of the paper a ainst the plate 30 are fast with therock sha t 34 mounted in the bearings 35 which form a part of thecarriage body, as shown in Fig. 6. At the center of this shaft 34 isfastened one end of an arm 7 36, the opposite or free end of WlllGhcarries the cam roller 37. The gripper hooks 33 are normally held closedor in contact with the plate 30 by means of the expansion spring 38, butwhen the roller 37 rides upon the cam track 39 as-shown in Fig. 11, the.

gripper hooks will be opened against the action of the spring 38 tomove-the glrip er hooks into one posltion and permit t e orward edge ofthe sheet to engage the front stops or rods 31. Immediately, however,the cam roller 37 of the gripper E rides or passes down the curved end40 of the cam bar 39,,the gripper hooks will be automatically throwninto closed position by the spring 38. The sheet S being thus grasped bythe gripper E, as shown inFigs. 13 and 14 is carried forward to the glueapplying device to have one longitudinal side ed e portion coated with astripe of glue. s the catalogue pusher'grippers have not up to this timebeen brought into active operation we will reserve a specificdescription of the same until deseribmg the part which such pusherggippers play in the wrappin operation. he glue-applying device, w ichis indicated as an entirety by the letter G, and b means of which theglue is to be applied to one side edge or flap of the sheet, as

shown in Fig. 27 at w, is preferably constructed as follows: Referringto Figs. 13 and 14, this glue-applying device G comprises the glue tank42 inwhich works the glue-wallower roller'43 which contacts with theglue-applying roller 44, the upper ortions of the peripheries of thesero lers' meeting above the glue tank, and these rollers 43 and 44 aregeared together by means of the gears 45 and 46. The glue. tank 42 iscarried by a. frame 47, the sleeve 48 of which slides on the rod 49,while a second sleeve 50 of this bracket is threaded and receives theadjusting screw 51 having the operatinghandle 52 at one end thereof. Byoperatlri the handle 52 in the required direction t e glue tank togetherwith the glue rollers and their accompanyin parts may be adjustedlaterally of the pa of travel raeaeoe of the envelop to the requisitedistance for properly applying a stnpe'of glue to an edge portion of thesheet, the degree of adjustment depending, of course, upon the widthofsuch sheet. The amount of glue on the wallower roll may be regulated andrendered uniform by means of a scraper blade 53 swin 'ngly mounted onthe stud 54 and adjustab e to and from the wallower roller by the setscrew 55. As will be seen from Fig. 14, the glue-applying roller 44 doesnot touch or contact with the portion of the bed B therebeneath, but isslightly spaced apart therefrom, and in order that the traveling sheetmay receive its proper stripe of glue a small angular guide plate 56 isprovided which is bolted to the adjacent portion of the bracket 47, asat 57, and the bottom of this guide is slightly inclined to thehorizontal so that the sheet in its pas-- sage will be moved upward inposition to contact with the periphery ofthe glue-applying roller andreceive the glue therefrom. After the sheet has received its stripe ofglue from the glue-applying mechanism it continues its forward traveland is brought beneath the catalogue-feeding mechanism which is adaptedto supply the catalo es successively, one for each wrapper s eet broughtinto position therebeneath; this catalogue-feeding mechanism beingindicated as an entirety by the letter H. Referring to Figs. 4 7, 8,9,15 and 16, it will be seen that it comprises an inclined table 58having spaced slots 59 through which partially project the pairs ofrollers 60 and over these rollers run the endless feed tapes or belts61. The catalogues shown at H are stacked on end on this inclined tableas shown in Fig. 4, suitable confining side boards 62 being mounted onthe right and left handv fed down to this position by the. endless tapesbefore referred to. -The catalogue which is in position to be fed to thewrapper mechanism rests against'this plate 64 and in contact with thepreferabl rubber faced rollers 65 and 66, the perip cries of whichproject through slots 67 and 67 in this place and thus slig tly beyondthe front face 0 the plate so the foremost catalogue will rest 'incontact with these rollers 65 and 66,

which are geared together in driving engagement to the endless chain 68,until the lowermost roller 66 is rotated by means of the intermittentgear 69, and its clutch connection shown in Fig. 10. This gear 69 inturn is driven through a mutilated gear 70 mounted on the shaft 71, asshown in Fig. 9,

aaeasee and this shaft 71 in turn is driven through the bevel gears'72and 72, the latter being mounted on the shaft 73, the bevel gear 74:of whichreceives motion throu h its corre-, sponding bevel gear 75 onthe s aft 76, this shaft having at 1ts opposite end a bevel gear 77which meshes with the similar bevel gear 78 on the vertical shaft 79,the latter being driven through the bevel gears.80 and .81, which inturn receive motion through the shaft 82 connected in driving engagementwith the sprocket shaft 26 through the bevel gears 83 and 84, thesprocket shaft 26 being driven as heretofore described. Thus the lowerfeed roller 66 will receive'an intermittent motion and in turn will.impart a corresponding motion to its companion roller 65. This willcause the contacting catalogue to be fed downward until its lowerportion.

contacts with the roller 85 mounted parallel with and beneath theroller66. The magazine will pass between this roller 85 and thecorrespondin roller 86 carried by the framework 0 the table 58, as shownin Fig. 4:, and, referring to this figure, 1t w1ll be understood thatthe table 58, the frame of .which carries this roller 86, is bodilyadjustable toward and from the catalogue-sup-' porting plate 61 b meansof the adjusting screw 87 threade in the screw sleeve 88 loose on thetie-rod 89, the frame of the table having slots 90 therein to permit ofthis. This arrangement is simply a to vary the opening or space betweenthe forward edge of the table and the plate 6 1 and between the feedrollers to ermit the handlin of catalogues of various thicknesses. hetwo rollers 85 and 86 are driven through the in:

termeshing gears 91 and 92, the gear 92 being driven through therelatively large gear 93 on the stud shaft 94:, this gear 93 havingintegral therewith a smaller gear 95 driven" from the gear 96 on theshaft 76, and it will be further understood that this gear 96 mesheswith and drives the gear 97 on the shaft 44 of the glue-applying roller4d so that motion will be imparted through the shaft 4 1' to the gears46 and 45 of the glue rollers thereby rotating the latter to insure thepresen tation of freshly glued surfaces to the sheets. The feed tapes orbelts 61 of the catalogue table 58 are intermittently driven bymeans ofthe intermittent bevel gears 98 and 98?,

the latter being on the shaft 99, which is geared through a pair ofspiral gears 100 to the shaft 101, of one of the pair of rollers 60, andby means of this intermitttent driving of the belt'6l the catalogueswill receive an intermittent feed toward the plate 6 1.- Asthecatalogues are fed down between the feed rollers 85 and 86, it is tobe understood that these latter rollers normally revolve. at a littlegreater s eed than the rollers 65' and 66. However, a er the cataloguehas passed in between these rollers 85 and '86 and is engaged thereby,so as to continue to feed ownward, the roller 66 will be revolved at agreater speed than is normally imparted to it y itsusual driving orpower transmission mechanism. This is accomplished by the ball andratchet clutch drive as will be seen by reference to Fig. 10. Thisroller 66 is loose on its shaft 66 and between this roller end of theroller 66 thereby driving the latter'in one direction. When the rollersand 86 draw the catalogue along at a greater speed than the normalrotation of the roller 66 this roller travels at the same speed as thecatalogue thereby reducing friction between the same, wh ch would occurif the roller 66 was rotati at its initial speed.

The catalogue being ed downward by the feedrollers 85 and 86 drops ontothe outturned ends 103 of the flat bars 104; these bars forming a gridbracket or support for the catalogue.

Now after the sheet gripper E has taken a sheet from the sheet feeder,as shown in Fig. 3,it carries this sheet along in the travel of theconveyer and past the glue applying device as indicated in dotted linesin Fig. 13, so that the stripe of glue X is applied to one longitudinaledge of the sheet, as before stated and as indicated in Fig. 27. It

will be-noted that the sheet is carried be tween a gripper E and one ofthe pusher grippers F. The construction of these pusher grippers will bereadily understood by reference to Figs. 24 and 25. Each pusher grippercomprises a carriage 105 surmounted by a plate 106 forming a platform.This carriage is provided with the four I wheels 107 traveling in thetrackways, the carriage of course being attached to the chains 11.Mounted on the axle 112 of the carriage is a depending yoke 113, thepar- .allel arms of which are formed with elongated slot's 114 throughwhich the axle 112 passes. This yoke carries an upwardly extendinghooked arm 115 which is adapted to engage the rear end of the catalogue,as hereinafter described. Loosely mounted upon the axle 112 between thearms of the yoke .is a collar 1l6 carrying an arm 117 provided at itsfree end with a cam roller 118. This collar 116 is also formed with aprojecting lug 119 bored for-the passage of the pin 12 0, thelower endof said pin. being socketed in the bight 121 of the yoke, and a coilexpansion spring 122 surrounds this pin 120 between the lug and thebight of the yoke. The normal tendency of the spring-is to hold thepushed in open position, with the cam the carriage the pusher gripperroller arm hanging vertically as shown in Fig. 24. When, however, in thetravel of reaches the cam bar 123 located beneath the sheet feedingmechanism as shown in Fig. 3, it will ride up the inclined face 124thereof, and the cam arm will be elevated so as to throw the hooked arm115 to the position shown in dotted lines 'in Fig. 24, and thus thepusher gripper may pass freely beneath the sheet feeding devices. Itcontinues in this position so long as the cam wheel 118 rldes on the bar123. At this point I might mention that, as indicated in Fig. 24, thispusher gripper has three distinct positlons which it may assume, that isto say, the w de open position indicated in full lines 1n said figure,the intermediate position as indicated in dot-and-dash lines wherein thehook of the arm 115 overlies the platform 106, but 1s elevated aconsiderable distance therefrom, and the final catalogue grippingpos1t1on, indicated in dotted lines in said figure wherein the hook ofthe arm is depressed toward the platform as when gripping the catalogue.

' These positions will be referred to later on,

but at the timethe pusher gripper is riding on the cam bar 123 it is, asbefore stated, moved to its depressed or dotted positlon to enable itto-safely pass thepaper sheet feeding guides.

Referrin to Fi per drops 0%lover t e rounded end of the cam bar 123 itflies to its open position, at which time the sheet is being drawnthrough the glue-applying device and the upward and backward. movementof the hooker arm 115 will lift up the rean end of the sheet, as shownin Fig. 4. The sheet is now broughtby the carrier directly beneath thecatalogue feeding device with the two grippers occupying the positionsshown in Fig. 4, and the catalogue which is resting upon the bracketgrid is tilted over and onto the sheet by the kicker blocks 125 fast onthe shaft 76 and which have been brought into position by the turning ofthe shaft into position to push the catalogue off the bracket, asshownin Fig. 15. The catalogue thusfalls face downward upon the sheetand is carried along thereon. In the progress of the carrier the camroller 118 of the pusher gripper rides up the inclined face 127 of thestepped cam Joar 128,

' and onto the level section 129.thereof, shown in Fig. 4. This causesthe hooker arm 115 of the pusher gripper to assume its intermediateposition shown in Fig. 17, and thus fold over the rear end lap s of thesheet on the catalogue. The continued travel of the carrier brings theforward end of the catalogue up against the rocking usher fingers 130,as shown in Fig. .16, an these pusher fingersshove the catalogueslightly rearward -on the wrapper sheet so that the rear end of thecatalogue will snugly seat or fit in Fig. 18. At this "1311118, ofcourse, both the 130 4, when the pusher grip aeaaoe this shaft is.rocked at proper intervalsthrough the link bar 132 connected at one endto the rod and at its opposite end as-at 133 to the lower end of arocking calm lever 134 mounted on the stud 135 carried by the frame ofthe machine, the upper end of this lever 134 having a cam roller 136operated by the cam 137 on the shaft 7 6. Extending parallel with theshaft 131, but somewhat in advance thereof, is a second shaft 138, whichis in the nature of a right and left hand screw thread and is operatedby a suitable handle 139. This shaft has threaded thereon a pair ofspaced sleeves 140 carrying the guide bars 141 which terminate at theirfree end in the vertically inclined guide arms 142. The sleeves 140 arepreferably connected through webs 143 with the sleeves 144 on the shaft131, these latter sleeves each carrying one of the pusher fingers 130.Of-course the vertical arms 142 and the side bars 141 act' ward. andfrom each other to accommodate hooks or catalogues of difierent widths.

As the carrier D with the catalogue in its wrapper held as shown in Fig.17 continues its travel, it brings these to the side folders 145, asshown in Fig. 18. These side folders which are. adjustable toward andfrom each other by means of the pin and slot connection 146 are of awell-known form, and together constitute a folder or former having aflaring mouth formedof the vertically inclined sides 147 graduallymerging into the inturned parallel sections 148 so that the two sidesections of the wrapper sheet will be folded over on the catalogue andin overlapping relation to the endflap .9. By reference to Fig. 18 itwill be seen that owin to the peculiar formation of the two fol ingplates, the unglued side 8 'of the sheet will be first folded over, andsubsequently the glued section 8 of the sheet will be folded over on thesection 8. These two folder plates 145 are adjustable toward and fromeach other by means of the right and left handed screwed shaft 149passing through the threaded sleeves 150 of the plates. Just before thecatalogue with its wrapper passes into the side folder, the cam roller118 of the pusher gripper rides up the second inclined wall 151 of thecam bar 128, and onto the top edge of this bar, as shown at the righthand side of Fig. 4, and this moves the hooked arm 115 to its finalor'dotted positionshown in Fig. 24, thus firmly gripping the end of thecatalogue and the end flap s overlapping the latter, in which conditionthe catalogue ,passes into the-side folder as indicated in menace ushergripper F sheet gripper E and the y wrapped cataowever, as the sheetgripetes the operation of drawing wrapped Catalogue through the and pastthe spring tension creasing blocks 152 which crease or press the sidefolders of the wrapper along the longitudinal-side edges of thecatalogue, this sheet gripper E rides up on the cam bar 153 and isopened thereby as shown in Fig. 19, thus 153,- as will be seen byreaches the releasing its hold on the package and then continues itstravel around the'sprockets, the gripper again closing by the actionOfltS spring immediately 1t leaves the cam bar reference to Fig. 20. Thepusher gripper F, however, pushing against the rear of the latterbeneath the works the glue roller 155, this roller receiving a rotarymotion through the intermeshing bevel gears 156 which may be given byany suitable power transmission gear. As the forward end section of thewrapper sheet 155 the terminals 157 of the rocking fingers 158, engagethe under faceof the end portion of the sheet, and as these fingers-rockupward on their shaft159, the end of the sheet shown at s in Fig. 20 ispushed against the glue roller and receives a coating of glue therefrom.The continued advancing of the package by the pusher grippenn'ow carriesit beneath the presser rollers 160 and 161, the presser roller 160 beingformed by a series of annular preferably rubber disks likewiseconstructed, but is preferably ten-, b

the intermeshing gears mounted in spaced relation on a shaft 162, andbetween which disks the fingers 158 project. The lower presser roller161 may be sioned and held up to its work by means of springs 163,yieldingly supporting the bearings of the shaft 164 of the lower roller.

The rock shaft. 159 receives its motion through the tooth segment 159'which meshes with the arcuate rack 165 at the upper end of the lever 166mountedto swing on the pivot stud 167, the lower end of this lever beingconnected at 168 to the link rod 169,

the latter in turn being pivoted as at 170 to the lever arm 171 mountedto rock back and forth on the shaft 172. The presser roll 160 has a gear160' which is driven through a gear 173 loose on the shaft 159, thisgear in turn being driven by a corresponding gear 174:, which alsomeshes with and drives the gear 161 of the roll 161. This gear 174=isdriven through the large gear wheel 175, and through this gear 175 arealso driven 176 and 177 which drive the gears 178 and 179 of the rearpresser rollers 178179. On the transverse rod- 180 are mounted thehangers 181 for the upper horizontal presser bars 182, which act italong withthe travel package carries the. glue pan 154 in which positionbeneath this glue roller 20 to 22 inclusive,

loose clutch gear member 193 -to bear against the upper surface of thecatalogue and properly guide the same to the rear or lastset of presserrolls.

The presser.

device J also includes a table-like support, 7

made up of the spaced parallel bars 183 upon which the catalogue restsin its travel through the presser, the rear terminals of these barsbeing rounded as at 183 to cause which works in the elongated slot 191in the frame 184, the operation of the hand shaft 187, through the trainof mechanisms just mentioned enabling the table 183 with its frame to beraised and lowered to accommodate catalogues of various thicknesses aswill be'readily understood.

Thus it will be seen by reference to Figs. that after the end flap s ofthe catalogue has had the glue applied thereto and has been folded overagainst the previously folded Side fiaps or sections of the sheet, asshown in Fig. 17, and the pusher gripper F has released the catalogue,by the action of the gripper passing off of the end 128 of the cam 128,the catalogue now completely wrapped will pass through the presserdevice J and the laps or joints firmly sealed so that the package. willappear as shown in Fig. 33, presenting a neat appearance, with thecatalogue completely wrapped and'with one flap tucked in utnot secured,so that it may be readily pulled out to remove the catalogue from thethat the sheet will be interposed between the gripper hook and theplatform plate of the gripper the machine will be automatically stopped,thereby preventing the dropping or feeding of a catalogue when no sheetis present to receive it. This is accomplished as followsz'The powershaft of the machine is provided with the usual clutch 193 normally heldin driven engagement with the by meansof the spring .19 1. The clutchshaft 195 is pivoted at 196 to the shipping lever 197 which is fulcrumedat its lower end at 198 to' a bracket forming part of the frame of themachine. This shipping lever 197 may be manuallyshifted by grasping thehandle 199, to throw the clutch out. It may also be thrown outautomatically to stop the mameshing with the gear 188 of the cam shaft189, the cam 190 of chine through certain electrically controlledmechanism of the general character shown in the patent to Reifsnyder andSchwerdtle, No. 1,171,804, dated February 15,1916. In the presentinstance the shifting lever 197 carries an electric solenoid 200, theplunger 201 of which carries the shipper yoke 202, which engages withthe grooved roller 203 sliding on the stud 204 also carried by theshifting clutch lever 197. The coil spring 205 normally tends to holdthis roller 203 out of the path of the cam 206 mounted 'on thecontinuously rotating shaft 207. As will be seen by reference to Figs.12 and 23, the platform plate of the gripper E is insulated from the bedof, the carriage 27. Connected to the underside of the bed of themachine but insulated therefrom, and located a short distance beyond thepoint where the gripper E should grasp a sheet is a contact plate 208 incircuit with the battery 209 and consequently with the solenoid 200, asdiagrammatically illustrated in Fig. 26. Now should the gripper hooksfail to grasp a sheet, the contact strip 210 on the carriage willcontact with the contact plate 208, and

the circuit will be closed to the solenoid, through the gripper hook,the contact strip 210, the contact plate 208, and the circuit wires,thereby energizing the solenoid, pulling inward on the plunger andbringing the sliding roller 203 in the path of the cam 206, the cam thuspushing on the roller and consequently throwing the lever 197 todisconnect the power clutch.

Should a catalogue fail to'feed, the lever will likewise be thrown outby the solenoid through the mechanism diagrammatically illustrated inFig. 26. To the back of the supportin bars 104 which form the bracketsgrid for olding the catalogue just before it is deposited on the sheetwe fasten and insulate a pair of contact brushes 211 between. which islocated the partly insulated rotating armature 212. Now at certain timesin the rotation of the armature, as

, when the insulated section thereof spans the brushes 211, no currentcan pass t h erethrough from the battery 209, while atother times thecircuit is closed at this point. When a catalogue drops onto thesupporting ends 103 of the bracket 104, it will depress the adjacent end213 of the rocking arm 214 and lift the end 215 of the latter out ofcontact with the arm 211 of the brush 211, so that even if the circuitis complete or closed by the rotating armature at that point, thecircuit to the ground or frame of the machine will be broken and thesolenoid will not be energized. However, should the catalogue not be fedthe end 215 of the arm 214 will rest upon the brush arm 211' and whenthe rotating armature closes the circuit between the brushes 211 thesolenoid will be energized, the clutch lever .197
